Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of displaying information recorded in an IC card on a display unit of a mobile phone, and more specifically, reading information stored in a storage unit of the IC card and reading a part of the information. The present invention relates to a method for temporarily downloading a program to be displayed on a mobile phone from an external device and displaying information on the mobile phone.

2. Description of the Related Art IC cards are gradually being adopted by the credit card industry and financial institutions because of their large storage capacity and high security. The IC card includes a memory card equipped only with a memory and a simple logic circuit, and a so-called IC card (CPU) (central control unit), RAM (random access memory), and ROM (read only memory) in addition to the memory. Also called a smart card.) The above cash cards used in the credit card industry and financial institutions are the above-mentioned highly confidential IC cards. On the other hand, in a system using a magnetic card, for example, in the case of a cash card, if the password is entered on the cash dispenser's keyboard to improve security, it will be checked against the password registered in the center computer of the financial institution. It is possible to proceed to the next operation only after being matched and
Safety is maintained. In the case of an IC card, the personal identification number is registered in the memory of the IC chip. When an IC card is used as a cash card, if the password is entered on the cash dispenser keyboard,
The collation work is performed in the IC chip of the C card. I
Since the C chip returns only "match" and "mismatch" signals, the personal identification number registered in the IC chip does not go out of the IC chip, and the stored information can be accessed only after the match. Therefore, it is said that the confidentiality is extremely high. Also, in the case of an IC card, there is no need to make an inquiry to the bank computer via a line (often a dedicated line) to confirm the personal identification number, or to drive the center computer of the bank. No waste of time.

There is also a demand for displaying recorded contents on an IC card having many merits as described above. Since the card has a large storage capacity as described above, the number of cases in which a plurality of applications are loaded and used on one IC card is also increasing. If the terminal is always near, you can check the recorded contents of these applications, but the terminal is not always available. Therefore, many inventions in which a display medium is mounted on the IC card itself and a display driver for displaying information and a power supply (battery) for display are mounted and disclosed. When functions become complicated in this way, IC
The price of the card itself will increase and the number of failure factors will increase.

[0004] Further, mobile phones have been able to realize an increase in memory capacity per unit area of an IC chip, high functionality, and cost reduction, and have continued to spread due to digitalization and high communication speed in the communication industry. In addition, the display section of a mobile phone is becoming more colorized and higher definition, and the screen is becoming larger. As mentioned above, the enormous memory and the faster communication speed have made it possible to import movies and import programs.
